INTRODUCTION

1.0 INTRODUCTION

The SolarFlow Plus design provides several methods for gaining access to data generated bySolarFlow Plus. This manual describes the SolarFlow Plus/Model 2251 Gas ChromatographController (2251 G.C.C.) Data Acquisition System (SFDAS) software package, which providesthe following capabilities for gaining access to SolarFlow Plus and Model 2251 GasChromatograph Controller data:

1. Retrieval of Data Logs generated by SolarFlow Plus

2. Retrieval of Event Logs generated by SolarFlow Plus

3. Database capability for storage, display, and printing of data and event logs retrieved fromSolarFlow Plus

4. Retrieval of 24-hour averages and active alarms from the Model 2251 Gas ChromatographController

5. Database capability for storage, display, and printing of 24-hour average data and alarmsretrieved from the Model 2251 Gas Chromatograph Controller

6. Direct channel access to SolarFlow Plus to change or fix channel variables; acknowledgeor change alarms; or view the Channel Zero Report.

The SFDAS program can be configured to retrieve data from up to a total of 100 SolarFlow Pluscomputers and/or Model 2251 G.C.C. units. The SFDAS program may be set to dial eachSolarFlow Plus computer at a predetermined time using a Hayes (or compatible) modem capableof up to 2400-baud communications.

SFDAS program provides three ways of communicating with SolarFlow Plus instruments:

- updating specified logs- retrieving all data/event logs- retrieving logs for specified days

SECTION 1 1-1


The SFDAS program requires that the location of a SolarFlow Plus computer unit and the methodfor contacting the unit be defined in order to communicate with SolarFlow Plus computers. TheSFDAS program disk includes a menu that allows the user to enter the phone number of theselected location and other parameters. The SFDAS system supports the Hayes Smartmodemprotocol. If a Hayes modem is connected to the PC, the SFDAS can place telephone calls to theselected location automatically at the time (or times) specified.

The SFDAS package is provided on one 3.5" floppy diskette. The software package is designedto run on version 2.1 MS-DOS or later. Backup of the Daniel-supplied diskette is essential.(Consult the DOS operating manual for diskette backup instructions.) The original SFDASdiskettes should be stored in a safe location. The files included on the diskette and those builtduring use of the program are defined in section 7 of this manual.

5.2.2.2 Event Log Format

The header block of data details the collection date and time, the Location ID and name, as wellas details the column headers for each of the events that are listed. Each Event that occurswithin SolarFlow Plus will be date and time stamped. The log will list a description for eachtype of event. The column titled "Number" serves multiple purposes depending on the eventtype; it may be an alpha description of the parameter changed, the channel number, or may beblank in some cases. The column titled "Value #1" relates to the value in the parameter priorto the event and the value under "Value #2" relates to the new value of the parameter after theevent. See the listing of event log types for more information.

The first four items under the header block relate to the set up operation performed on theSolarFlow Plus during the start up sequence with the HHDT. The first event indicates that thecalculation module "STKD DP WATER" was activated. The second event indicates that the UnitName was changed from "BLANK" to "CELL 1". The unit name was downloaded to the slavein the third entry and the fourth entry changed the Unit ID from "BLANK" to "123". TheColumn headers Value #1 and Value #2 relate to before and after values respectively.

EVENT LOG ACCESS5-4


The fifth item in the log shows that channel number 20 was placed in the fixed mode. Channel20 for this application was the meter pressure transmitter. The value of that channel was fixedas shown in the value #2 column as 1.

The sixth item shows that a user logged on with security code 120 at the displayed date and time.In lines seven and eight the user collected an Event Log and a Data log. The Value #1 and #2parameters relate to the start and stop date/time frames for the collections, the "0000000000"under value #1 for the Event Log signify that the first entry collected was at the startup time ofthe SolarFlow Plus which is defaulted to all zeros. The key for decoding the ten digit numberis as follows:

Y Y M M D D H H M M8 7 0 7 3 1 1 1 0 0

This represents the following Date/Time July 31, 1987 11:00 am.Some Date/Time values will be 14 digits in length, for example when a time change is made theuser would see a value similar to the following:

Y Y M M D D H H M M S S d d8 7 0 8 0 2 0 6 3 9 3 0 0 1

This represents the following Date/Time/Day of WeekAugust 2, 1987, 06 hour, 39th minute, 30th second, first day of the week. The d d relates to theday of the week; 01 = Sunday, 07 = Saturday.

Lines 9 through 14 show a typical analog input calibration sequence where the operator loggedonto the unit and proceeded to calibrate channel 23, which in this example is a differentialpressure analog input. The value for channel 23 was temporarily fixed in line ten to 41.0 inchesH2O which was the live value at the time the calibrate menu was entered. Lines 11, 12, and 13display the Low, High, and Low Bias calibration points for the calibrated channel number 23.Line 11 relates to the Low calibration point, line 12 equates to the High calibration point, andline 13 relates to the Low Bias calibration point. The values under columns "Value #1" and"Value #2" relate to the raw value sensed by SolarFlow Plus, and the value given to SolarFlowPlus by the user via the HHDT during the calibration sequence. Line 14 indicates the date andtime that the channel being calibrated was returned to its previous state along with a presentvalue for the channel.

SECTION 6

AUTOMATIC DATA COLLECTION

6.0 COLLECTING DATA AUTOMATICALLY

The SFDAS program can automatically collect data from as many as 100 SolarFlow Plus unitsand Gas Chromatograph Controllers. Collection may be scheduled at specific times of the day,at specified intervals or immediately. The collection sequence may be set up to repeatcontinuously or it can be set up to execute collection once and terminate.

NOTE: Before beginning an extended automatic collection session, makesure that ample room is available on the disk for your log files.You may collect data from up to 10 filenames at one time.

6.1 AUTOMATIC DATA COLLECTION

The Automatic data collection can be accessed from the Main menu of the SFDAS program usingthe F4 function key. The following procedures presuppose that you have set up automatic datacollection and established the data desired. If you have notdefined your automatic datacollection setup, proceed to section 6.2 and perform your set-up procedures first.

a. Press the F4 function key on the Main Menu. The following screen appears.

Automatic Data Collection

Menu Options:

F1: Start Automatic Data CollectionF2: Change Automatic Collection Control File

ESC/ALT-X: Return To Previous/Main Menu

Your Choice?

SECTION 6 6-1


b. Press F1; the screen asks for a file name. Enter the file name(s) to start the automaticdata collection.

Automatic Data Collection

Enter Automatic Collection Control Filename:

Default Automatic Collection Control File is: TMP2.ACL

List of Automatic Collection Control Files are:

TMP2.ACL TMP1.ACL

Another method of obtaining automatic data collection is to start from the DOS prompt bytyping:

SFDAS AUTOCL "Filename 1...Filename 10" <ENTER>

The program automatically executes automatic data collection. To exit the SFDAS programautomatically after collection, place a "/E" after your list of Filename(s); type:

SFDAS AUTOCL "Filename" /E <ENTER>

Execution of the automatic collection sequence defined in the Collection Control File beginsimmediately. Progress of the sequence is provided by messages displayed on the monitor. Thesequence can be aborted by pressing the escape key. If the sequence is not aborted, it continuesuntil it encounters the end of the collection control file(s).

6.2 AUTOMATIC DATA COLLECTION CONTROL FILE SETUP

Before Automatic Data Collection can be started, the collection sequence must be defined bycreating an automatic collection control file. An automatic collection control file is created usingfunction key F2 from the Automatic Data Collect Options menu. It would be a good idea tobecome familiar with the edit and insert mode commands (sections 6.2.1 and 6.2.2) beforestarting your setup.

AUTOMATIC DATA COLLECTION6-2


6.2.1 Edit Mode

Changes can be made to the collection control file while in the EDIT mode. Changes are madeby positioning the cursor on the line at which the change is to be made. The cursor is positionedwith the PgUp, PgDn, Up arrow, and Down arrow keys on the PC keyboard. The change ismade by pressing a function key (F1 through F3) shown at the bottom of the screen. A briefdescription of each of the function keys is provided as follows.

F1-INSert-- Pressing F1 returns the program to the INSERT mode described in section 6.2.2.Lines added in the insert mode follow the record adjacent to the cursor at the time F1 is pressed.

F2-DELete-- Pressing F2 deletes the line adjacent to the cursor from the collection control file.

F3-CHG-- Pressing F3 provides for changing the current line in the collection control file. Afterpressing F3, operation of the program continues as in the INSERT mode except that thecommand entered replaces the line adjacent to the cursor at the time F3 is pressed. While in theF3-CHG mode, the word CHANGE is displayed on the monitor to the right of the command linebeing changed.

F4-FINISH -- When editing of the collection control file is completed, pressing F4 closes thecollection control file and returns the program to the Main Automatic Data Collection screen.

6.2.2 Insert Mode Commands

F1-COLLECT/POLL-- This command enables the specification of a selected log or logs so thatthis data may be collected from a particular Location/Unit. When the F1 key is pressed, anadditional menu appears which allows the selection of the type of log that will be collected. Onecan choose to collect the Data, Event, Channel, Miscellaneous, or All logs. After the log typeis selected, a prompt requests a 4-character abbreviated location/unit identifier for the desiredlocation/unit. This identifier is checked by the SFDAS program to ensure that it exists in theAcquisition Directory. If the identifier does not exist in the directory, an error message isdisplayed. Note that this entry is case sensitive, e.g. TMP2, not tmp2. If the Location/Unit intwo successive COLLECT commands has exactly the same telephone number, the SFDASprogram does not hang up the telephone until data from both locations/units have been collected.If the location is a Gas Chromatograph, any COLLECT/POLL selection will cause thechromatograph log to be uploaded.

SECTION 6 6-3


F2-PAUSE -- This command allows a period of time to be specified for interrupting theautomatic collection sequence. When the time period expires, automatic collection continues.When the F2 key is pressed, a prompt requests the desired time in hours and minutes in theformat, HH:MM. (The time must be entered as 02:30, not 2:30.)

F3-AWAIT -- This command is similar to PAUSE (F2) except that AWAIT interrupts automaticcollection until a specific time-of-day rather than for a period of time that can occur at anytime-of-day. When the F3 key is pressed, a prompt requests the time-of-day when automaticcollection is to continue in hours and minutes (using the 24-hour time format, HH:MM.) Forexample, if 15:00 is entered, automatic collection is interrupted when the command isencountered and resumes at 15:00 (3:00pm).

A wild card hour may be used by entering a double asterisk (**) for the hour. When theprogram encounters the AWAIT command with "**" entered for the hour, the current minutesare compared to the minutes in the AWAIT command. If the current minutes are greater thanor equal to those in the AWAIT command, the SFDAS program makes the following hour (thecurrent hour plus one) the hour for executing the AWAIT command. If the current minutes areless than the minutes in the AWAIT command, the program makes the current hour the time forexecuting the command. This allows for independently defining periodic collection sequencesregardless of the starting time.

F4-REPEAT -- The REPEAT (F4) command provides for applications in which automaticcollection runs continuously. When the program encounters the REPEAT command, theautomatic collection sequence starts at the beginning of the collection control file.

F5-IF-ENDIF -- A block which is only executed at certain times or on certain dates can be setoff by the IF TIME/DATE and ENDIF statements. When the F5 key is pressed, an additionalmenu appears in which TIME, DATE or ENDIF can be selected. If the user selects time or date,a prompt requests the entry of a time or date value. Time is entered in HH:MM form and dateis entered in MM/DD form. The HH and DD parameters may be replaced by the wildcardparameter, **. All statements following an IF up to the matching ENDIF statement, will beexecuted only if the current date matches the date in the IF statement. For time values, thestatements within the block will be executed once within the hour following the time given inthe IF statement. Each IF must have a matching ENDIF, and IF blocks may be nested. Theautocollect editor cannot be exited until there is a matching ENDIF statement for each IF.



F6-DOS -- The DOS (F6) command provides for inserting any DOS command, batch file(*.BAT), or executable file (*.EXE or *.COM) into the automatic collection file run stream.When this option is selected, the program requests the entry of a filename (*.EXE or *.BAT) torun or a DOS command. The filename or DOS command may be up to 40 characters in length.No error checking is provided for this inputand care must be taken to ensure that the entry iscorrect. As the program executes the collection file statements, the DOS statement is executedin whatever logical sequence it has been entered.

NOTE: Ensure that the execution of a DOS statement allows for returningto the SFDAS program. If for any reason the spawned DOS callrequires an input by the user, the system waits for that input beforecontinuing execution. The subsequent return to the SFDASautomatic collection sequence will be delayed accordingly.

F7-PRNT -- The PRNT (F7) command provides for printing a report on the printer for theSolarFlow Plus or a Gas Chromatograph Controller. For SolarFlow Plus logs, one can select toprint the Data, Event, Miscellaneous, Channel or all logs. Any of these selections will allow theprinting of a Gas Chromatograph log.

NOTE: If multiple data sets are stored in the file, a report is printed foreach data set.

ESC-EXIT -- Pressing the ESCAPE (Esc) key on the PC keyboard puts the program into theEDIT mode.

APPENDIX A

HAYES 2400 AND 2400B MODEM SETTINGS FOR SFDAS PROGRAM

A.1.0 The default configurations of the Hayes 2400 and 2400B modems are stored in anon-volatile memory. When these modems are used with the SFDAS program, themodems should be in the factory default configuration. If the modem’s non-volatileconfiguration has been modified then it will need to be set back to the factory default.The SFDAS program resets the modem to the configuration in non-volatile memory whenit initiates a call to a unit. Either a communications package (such as PROCOMM,XTALK, BITCOM, ETC.) or a resident DOS program may be used to set the factorydefault configuration in the non-volatile memory of the modem. The commands to resetthe modem to factory default configuration are detailed as follows:

A.1.1 Method Using Communications Package

a. Send the command: AT&F&W <cr> from within the communications package to theHayes 2400 or 2400B Modem through the appropriate communications port (COM1 orCOM2).

AT&F&W <cr>------ ----

Enter key, return key, control m

Write active configuration tonon-volatile memory in modem

Retrieve factory default configurationto active memory in modem

Hayes modem attention command

APPENDIX A A-1


A.1.3 Method Using DOS to set-up modem

a. Using DOS to set-up the modem requires several steps to create; but with a Batch file itcan be executed very easily.

b. To set the baud rate of the communications port connected to the modem, make sure thatthe program "MODE.COM" is accessible on one of the disks in the computer. Thisprogram sets the baud rate of the communications port connected to the modem. Writea small document file using DOS commands that will be sent to the modem. Follow theexample below:

C:\>copy con HAYES <enter>

AT&F&W <enter>

<F6 or control z (^z)>

This file will reside in the root directory of the drive C or it could be created on another diskdrive in place of C.

c. Whenever these modems are to be used with SFDAS the following sequence should beused:

C:\>DOS\MODE COM2: 2400,n,8,1 <enter>

COM2: 2400,n,8,1,-

C:\copy HAYES COM2: <enter>1 file(s) copied

The modem has now been configured properly for operation with SFDAS.

HAYES 2400 AND 2400B MODEM SETTINGS FOR SFDAS PROGRAMA-2


d. A batch file can be created to perform all of the routine functions described previouslywith the following commands:

C:\copy con SFDAS.BAT <enter>C:\DOS\MODE COM2: 2400,n,8,1copy C:\Hayes COM2:cd\SFDASSFDAS<F6 or control z (^z)>

This batch file can be executed by typing "SFDAS" at the DOS prompt. Several items mightchange depending on the computer being used. The preceding example assumes that there is nopath declared, the default drive at the DOS prompt is C, communications port 2 (COM2) isconnected to the modem, the SFDAS program has been transferred from the master diskette toa sub-directory named "SFDAS", and that file "MODE.COM" is located in a sub-directory named"DOS".
